Samsung Galaxy s6 has a screen density of 577 ppi which maps to xxhdpi - xxxhdpi
Screen resolution: 1440 X 2560
Samsung Galaxy S3 has a screen density of 306 ppi which maps to xhdpi
Screen resolution: 720 X 1280
My app with a lot of scenic images was developed against xhdpi-devices (i.e. S3)
but to have margins against the future the images has a resolution of:
Image resolution: 1300 X 1950
So - what happends with images with this resolution when put in a xxxhdpi device such as Galaxy S6? I compiled the app against an S6 and cannot see any
difference. Is this because the images are in the xhdpi-folder and s6 thanks to
this does not use the full density of 577 ppi? My theory - IF it have used the
full capacity - the images whould have been stretched out since the width is 1300 px and the screenwidht of S6 is 1440.
Greatful for answers
EDIT: the images uses the whole screenwidth.

I have added one splash screen image(1440 X 2560) in background. When I run the app, I see the image as stretched for the Samsung S8(All xxx devices).
Samsung Galaxy S7 resolution: 1440 x 2560 - XXXHDPI
Samsung Galaxy S8 resolution: 1440 x 2960 - XXXHDPI
The issue is if I am adding image(1440 X 2960) in a drawable-xxxhdpi folder, then image will be compressed for Samsung S7, and if I am adding image(1440 X 2560) in a drawable-xxxhdpi folder, the things will be bad in Samsung S8 device.
Is there any way through which we can manage the different images in our resources folder for different XXXHDPI devices?
I tried my way and it worked, try to create a drawable-long-xxxhdpi folder in res and put the 1440x2960 pixel image there. Hopefully can
I need info about under which dpis both Samsung Galaxy s5 and Samsung note 4 like do they come under xxhdpi or xhdpi or hdpi ?
S5 :
xxhdpi (~432 ppi pixel density)
note 4 :
technically it is DENSITY_560 since it has ~515 ppi pixel density ,
but you should target xxxhdpi and let the android resources system scale images down for you like the nexus 6
Can anyone tell me which Drawable does Nexus 6 and Nexus 9 support xxhdpi or xxxhdpi? I also want to whether Nexus 6 supports large- hdpi or anything else?
I searched in google but found no luck?
Thanks.

Nexus 6 has a quantized density of 560 dpi, which falls in between the
xxhdpi and xxxhdpi primary density buckets.
For the Nexus 6, the platform will scale down xxxhdpi assets, but if
those aren’t available, then it will scale up xxhdpi assets.
drawable-xxxhdpi/ # Higher resolution assets for Nexus 6
The Nexus 9 is a premium 8.9” tablet with a screen size of 2048 x 1536
pixels (288 ppi), which translates to 1024 x 768 dip. This is a 4:3
aspect ratio, which is unique compared to earlier tablets. The Nexus 9
falls into the xhdpi density bucket, and you should already have
assets in the drawable-xhdpi folder.
Nexus 6 is under the xxxhdpi device category just like the Nexus 6P,
Nexus 9 comes under the xhdpi category.

I am trying to create an application that I want to run on both Samsung Galaxy S3 and the Nexus One. But later I came to know that both the devices comes in the normal screen size. How can I make the layouts that fits both the devices?
What type of folders should be created and any entry in the menifest for that folders..?
Samsung galaxy s3 - 4.8 inches(Normal screen)
Resolution - 720 * 1280
XHDPI
And
Nexus one -
3.7 inches(Normal)
480 * 800
HDPI
A single layout(normal) should be fine for both the devices . You can create different set of images for both as one is hdpi and other is xhdpi.
Edit : Adding the example table
MDPI X Large 10.1 inches 1280w * 800h(landscape) Samsung Tablet
MDPI Large 7 inches 1024h * 600w HTC Flyer
MDPI Large 7 inches 976h * 600 w Samsung GT P6620
I have Galaxy tab 10.1 inch and I have made app and test on it, it works fine.
Now my question is will this app work on Galaxy 7 inch, Galaxy 7.7 inch, Galaxy note and Galaxy 8.9 inch
here is the details of these devices:
(My Device) Galaxy tab 10.1 inch --> 800 x 1280 pixels, 10.1 inches (~149 ppi pixel density)
Galaxy 8.9 inch--> 800 x 1280 pixels, 8.9 inches (~170 ppi pixel density)
Galaxy 7.7 inch --> 800 x 1280 pixels, 7.7 inches (~196 ppi pixel density)
Galaxy 7 inch --> 600 x 1024 pixels, 7.0 inches (~170 ppi pixel density)
Galaxy Note --> 800 x 1280 pixels, 5.3 inches (~285 ppi pixel density)
Please tell me for which device I have to make layouts again and what will be the folder names for drawable and layout
for Galaxy 7 inch --> 600 x 1024 pixels, 7.0 inches (~170 ppi pixel density) you can make layout folder with name "layout-large-mdpi-1024x600"....but for other device i am also unable to sort correct
As long as you are using relative layout mechanisms, it wil be ok. If you want to test it yourself, you can start your application in emulators using different screen sizes. There is also a Galaxy Tab Emulator.

Multiple Screen Resolution Support
Found answer myself: In order to support maximum devices, we can try to make a general layout which fits for all device, there may be minor trade offs, but one can live with that. We can make such a layout by using Relative Layout as much as possible, if there comes a situation where you can not handle multiple device support, we can try handling it with code at run time, but in such a manner, that it runs on all device.
